Hi,
I have installed latest upstream master on RHEL7.2. When i try to put
a host in maintenance which runs HE vm i see that vm does not get migrated
to another host and host is stuck in "preparing for maintenace" state. I
see the following errors in the vdsm.log . Can you please help me
understand why this error is seen?
seems to be caused by OVS hook issue
update to latest and try again, if it’s still not working remove the ovs
hook(s)
This VM was created in a version that was missing the graphics parameter,
so I do not think an upgrade will help.
Maybe shutting down the VM after the system upgrade may help, but that is
not always practical.
The patch that aimed to fix this is this: https://gerrit.ovirt.org/#/c/64300
Unfortunately it is stuck on review.
